ABSTRACT:
The invention relates to a reflector for an infrared radiating element. The reflector comprises a metal foil coated with—a first oxide layer deposited on the metal foil; —an infrared reflecting metal layer deposited on said first oxide layer; and—a second oxide layer deposited on said infrared reflecting layer. The first oxide layer is functioning as a diffusion barrier layer and is preventing the diffusion of the metal of the infrared reflecting layer in the substrate. The second oxide layer is functioning as a protective layer for the infrared reflecting layer giving the infrared reflecting layer the required thermal stability.
